18QHTF21-15.750-PD

Oscillators Overview

The 18QHTF21-15.750-PD is a 15.75 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates as a standard XO with LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby function for power down capabilities. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Oscillators Feature Summary

• LVCMOS output interface
• 1.8V operating voltage
• Standby power down mode

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply rail is stable and within the specified operating range to ensure reliable oscillator performance. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS clock source is required in a minimal footprint. Consider the standby feature if power management during idle states is critical. Compare alternative frequencies from the same series if the exact 15.75 MHz rate does not match the target application needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically offers various standard frequencies with consistent electrical characteristics and packaging. The PD suffix indicates specific ordering or tape/reel configuration details defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes must match the 15.75 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pin compatibility and thermal specifications before swapping. Consult the manufacturer's cross-reference list for validated equivalent parts.
